IP2003APBF Datasheet | International Rectifier

Features : Full function multiphase building block Output current 40A continuous with no derating up to TPCB = 100°C and TCASE = 100°C • Operating frequency up to 1.0 MHz .. • Proprietary packaging enables ultra low Rthj-case top • Efficient dual sided cooling • Small footprint low profile (9mm x11mm x 2.2mm) package • Optimized for very low power losses • LGA interface • Ease of design Description The i P2003APb F is a fully optimized solution for high current synchronous buck multiphase applications. Board space and design time are greatly reduced because most of the ponents required for each phase of a typical discrete-based multiphase circuit are integrated into a single 9mm x 11mm x 2.2mm power block. The only additional ponents required for a plete multiphase converter are a PWM controller, the output inductors, and the input and output capacitors. i POWIR technology offers designers an innovative board space saving solution for applications requiring high power densities. i POWIR technology eases design for applications where ponent integration offers benefits in performance and functionality. i POWIR technology solutions are also optimized internally for layout, heat transfer and ponent selection.

ENA BLE W hen set to logic level high, internal circuitry of the device is enabled. W hen set to logic level low, the PRD Y pin is forced low, the Control and Sychronous switches are turned off, and the supply current reduces to 10µ A. T T L-level input signal to M OSFET drivers. Power Ready - This pin indicates the status of EN AB LE or V D D . T his output will be driven low when EN ABLE is logic low or when V D D is less than 4.4V (typ.). W hen EN AB LE is logic high and V D D is greater than 4.4V (typ.), this output is driven high. T his output has a 10m A...
